This Week: Matthew Wars leaves She & Him and Monsters of Folk for his own sound; Alabama Shakes drop a great debut and pick up a spot on Jack White’s new tour; A collection of early 7-inches and LPs on The Dawn of Eternal Summers; Bassnectar’s speaker-splitting dubstep; Sisters Cristi Jo and Jezzica Zambri’s second effort.

There’s a reason The Muppets still hold a special place in our silly hearts. Now, a tribute album is on its way, celebrating the original songs from their five year run on CBS from 1976 to 1981, and covered by My Morning Jacket, Weezer, The Fray, Andrew Bird and more.
